Well, I could try... for a laugh, like...
Al-Lad is the happy kid, always smiling, never dirty, entertains himself, sleeps whens he's supposed to...
LSz is the moodier teenager, stays up longer, less tidy, louder, more in your face...
LSD is like tough uncle, uncompromising, unforgiving, stays up well late, but filled with insight & life experience...
1P-LSD is the tough uncles wife, auntie Similar, she's the same, seen everything & teaches it, she's up late too & takes no shit at any time of day...
